# NASA's lunar south pole location choice for Project Ignition represents an architectural commitment to ISRU-first development where base positioning follows resource location rather than accessibility

Project Ignition's three-phase architecture reveals a fundamental shift in NASA's cislunar strategy. The south pole location was selected specifically for water ice access in permanently shadowed craters, not for ease of access or communication advantages. Phase 1 allocates $10B of the $20B total budget to robotic validation, with MoonFall hoppers designed for 50km propulsive jumps to prospect water ice and CLPS accelerated to 30 landings starting 2027. This is not incidental infrastructure—the entire architecture is built around proving and exploiting ISRU from the start. Administrator Isaacman's simultaneous cancellation of Gateway (the orbital logistics node) reinforces this: NASA has chosen surface-direct over orbit-first, betting that water ice at the poles is valuable enough to justify the harder landing site. This represents NASA formally adopting the 'water as strategic keystone resource' thesis that was previously speculative. The architecture doesn't hedge with orbital depots or equatorial sites—it commits fully to the resource location.
